Leave-On Hair Serum with Collagen and Hyaluronic Acid
Three Bio2You hair serums — three different focuses, just like the three shampoos and three masks. The silk serum delivers smoothness and shine. The HairDensyl serum adds volume and vitality with a six-ingredient complex. This collagen serum is the simplest and most direct — two actives addressing two main problems: lack of moisture and lack of volume. And unlike the shampoo and mask — they stay on your hair all day.
Why a Collagen Serum on Top of Shampoo and Mask
In the collagen shampoo, contact with hair is 1–2 minutes. In the mask, 3–5 minutes. In the serum — all day. This means:
- Hydrolysed collagen can fully wrap the hair fibre and deliver lasting volume that holds from morning to evening — not just the first hour after washing.
- Hyaluronic acid can continuously bind moisture from the surrounding air, maintaining the hair fibre’s elasticity all day. Dry hair is brittle hair — when moisture is maintained consistently, hair breaks less and looks more vibrant.
Almond Oil Ester — The Shared Base
Almond oil polyglyceryl-4 esters are present in all three Bio2You hair serums — the shared base that gives hair softness without greasiness. Not ordinary almond oil but its soluble derivative — so hair feels light and shiny, not heavy and weighed down.
Antioxidant Protection
- Sea Buckthorn Fruit Extract — antioxidant protection for hair and scalp all day. In a leave-on formula, sea buckthorn antioxidants are more effective than in a rinse-off shampoo.
Conditioning
- Polyquaternium-7 — a conditioning polymer creating a lasting protective layer in a leave-on formula. Reduces static and flyaways.
- Glycerin — a humectant.
Texture and Feel
A lightweight, fluid serum in spray format. A fine mist that settles evenly on hair. No greasy or sticky feel. Hair feels fuller and more hydrated after application — collagen’s thickness combined with hyaluronic acid’s moisture.
How to Use
- Spritz onto clean damp or dry hair from 20–30 cm distance.
- Focus on hair length and ends.
- Comb through or let it absorb.
- No rinsing needed.
- Can also be used during the day to refresh volume and moisture.
